Specification of Letters Patent. Patented Apr, 26 1910, Applicationfiled September 30, 1907. Serial No. 395,160.

To all whom it may concern:

Be it known that I, MORRIS F. SMITH, a citizen of the United States, anda resident of the city of Philadelphia, county of Phil'- adelphia, andState of Pennsylvania, have invented certain new and useful Improvementsin Profiling-Machines, of which the following is a full, clear, andexact description.

My invention relates to improvements in profilers, and particularly tothat class of profilers in which a cutter is guided through apredetermined path by means of a pin which is moved over a fixedtemplet.

Profiling machines usually have two or more cutters, including aroughing cutter and a finishing cutter, actuated by separate spindles;the roughing cutter being used first to reduce the work to approximatelythe desired shape, this cutter then being moved out of position and thefinishing cutter being brought into position to complete the operation.I-Ieretofore these cutters have both been driven simultaneously,although only one of the cutters could be used at a time; thus needlesspower was consumed in driving the idle cutter and there was unnecessarywearing of the parts of the machine not performing any useful function.

The main objects of myinvention are to provide a profiler with thefollowing improvements; driving mechanism by which a cutter is drivenonly when in operative position; mechanism by which a cutter may bequickly and conveniently moved into or out of a predetermined fixedoperative position; a counterbalance for each cutter so that when thecutter is released from its lowermost operative position it will beautomatically raised to its uppermost inoperative position; means forpreventing undue wear and shock upon the cutters; means for raising andlowering the cutters; means for moving the cutters laterally; anautomatic system inclosed within the standard of the profiler forlubricating the cutters; and other improvements which will appear in thefollowing specification.

In the accompanying drawings: Figure 1 is a front elevation of aprofiler constructed in accordance with this invention; Fig. '2 a sideelevation partly'in section of the same; Fig. 3 a front elevation of thecutter carriage;

Fig, 4 a bottom plan view of the cutter carriage; Figs. 5 and 6 top planviews showing the carriage in two positions; Fig. 7 a verticaltransverse section of the carriage and support; Fig. 8 a longitudinalsection of the carriage and its support online 8- 8 of Fig. 7; Fig. 9 avertical longitudinal section of the carriage on line 99 of Fig. 7 Fig.10 a diagrammatic front View of the carriage with its bed 7 plateremoved showing the means for moving the cutter spindles vertically;Figs. 11 and 12 top plan views showing a modified form of drivingmechanism in two positions; Figs. 13 and 14 top plan viewsshowing asecond modification of the driving mechanism in two positions; Fig. 15is a left hand side elevation of the modification shown in Figs. 13 and14.

The profiler comprises, broadly: a main vertical hollow standardconstituting the body or support of the entire machine; a horizontaltable for holding the work, movable, longitudinally and laterally, andsupported upon a vertically movable bracket mounted upon the lower frontportion of the frame; a pair of'vertical cutter spindles, verticallymovable and carried by a horizontally movable cutter carriage slidablymounted above the table upon the upper front portion of the frame of themachine; a rotary handle, a g'ear'and a rackfor moving each spindlevertically; a'l'atcli for securing the spindles'in fixed positionsvertically; a spring for automatically elevatin the spindles'whenreleased from their locked positions; a rotary handle, a'gear and a rackfor moving the cutter carriage horizontally; and a latch for locking thecarriage in a fixed position. i

The preferred driving mechanism of the machine comprises, broadly: apair of horizontal pulleys carried upon the upper side of the cuttercarriage, concentric respectively with the spindles and having splinedconnections therewith, so that the spindles may be driven by'the pulleyswithout supporting them; a vertical shaft extending centrally throughthe frame of the machine,

journaled in-bearings carried thereby, havdrive shaft by inter-meshingbevel 'ears to drive the machine.

Referring to the drawings, particularly to Figs. 1 and 2, it is seenthat the vertical standard or body 1 of the profiler is provided at itslower end with laterally extending sides 2, having upturned edges 3, andforming the base of the machine. The lower front portion of the standardis provided with vertical parallel ways l, upon which is slidablymounted a bracket 5, which is provided upon its upper side with ways (3extending l1e"'=izo"ally in av direction substentiri erpc scalar to thefront plane of the machine, and slidably carrying table bed 7,supporting upon its upper side the table 8 which is mounted to slide,with respect to the bed, direction parallel to the front plane of themachine. The usual mechanism is provided for elevating the table byraising the bracket supporting it, and for moving the table eitherlongitudi nally or laterally of the machine. Such mechanism being old, afull detailed description is not necessary, as this feature of themachine will be sufficiently understood from the drawings.

The frame of the machine is curved, from a point at the top of thevertical ways supporting the table, rearwardly away from the inner edgeof the table, and then extends vertically and is again turned forwardlyand extends horizontally above the table, terminating in a substantiallyvertical flat surface formed by horizontally extending spaced ways orguides 9 which form the upper and lower edges of the front upper portionof the standard and extend longitudinally of the machine, projectingbeyond the sides of the standard in each direction, being suitablyconnected at their ends by cross bars 10, the space between the barsopening into the interior of the standard.

The cutter carriage, which is slidably mounted upon the horizontal waysof the standard has a vertical bed plate 11, the upper side 12 of whichis extended inwardly and provided with a groove fitting over the upperedge of the upper guide 9 to support the carriage, the lower side of thecarriage being similarly extended over the lower edge of the lowerguide.

Mounted upon the front of the carriage bed are a pair of verticallymovable sliders 13, the inner side of each slider being formed in theshape of a dovetail ll. and resting in a corresponding groove in thecarriage bed. The upper and lower ends of each slider are provided withforwardly extending lugs 15, provided with taper sockets and carryingsplit bearings 16 held in the sockets by means of nuts 17 and lock nuts18. Hotatably supported in these hearings are the vertical cutterspindles 19, the spindles be ing secured against longitudinal movementwith respect to their bearings by collars 20 secured to the spindles, orby any other suitable means. The upper end of each spindle passesslidably through a bearing 21, which projects over the front of the bedand is secured to the upper ed e of the bed by means of screws Thisbearing is formed externally into a i upwardly extending cylindricalbearing concentric with the spin lle, and supports a pulley 2%, the hubof which rests at its lower edge upon the shoulder 25 of the beari Theupper edge of the hub of the pu is provided with a collar 26, secured tothe hub by means of screws 27, and projecting over the upper end of thepu ey and slidably receiving the spindles 19, through the aperture ofthe coi the s .dles being provided with lon diral key-way 28, and thecollar being p led with. a corresponding spline 28' whereby motion istransmitted from the pulley to the spindle, the spindle being free toslide vertically and the pulley being fixed in a vertical position andbeing supported dir ctly upon the bed of the carriage. Looselysurrounding the spindle and between the collar 26 and the upper end ofthe bearing 23 is a washer 26 which is rigidly secured to the end of thebearing 23 by means of the screws 27'. The outer --dge of this washer 26extends outwardly beyond the surface of the bearing 23 and engagesloosely in a recess provided therefor in the upper end of the hub of thepulley Vertical movement is given to the spindles by means of thevertical racks (see 8) which are rigidly secured to the bed of thecarriage, and gears meshing respectively with the racks, e h of thegears being mounted upon the r end of a shaft 31, which extendsrotatably through tl e slider supporting the spindle, in 1-: suitablethimble 82, and has secured to its outer end a crank 33 and c 'ankhanfhe whereby the gear may be rotated, this moving the slider verticlly and carrying therewith its spindle. Concentricwith each gear 30 andrig idly secured to the inner face thereof is a pulleyilfi havingagrooved face 36. Extending in the grooves of each pu ley 1* 1d eonnectithe two pulleys togetlter is spir 37, each end of the spi beirg see nits corresponding pulley by means of a plate 38. lVhen either pulley ismoved out of the horizontal plane of the other. the length of the springis increased, and the tension upon the spring is suflicient to rotatethe lower pulley vertica y along its rack, thus automatically QlGVElt]the corresponding spindle.

A horizontally movable latch 39 (see Fig. 10) is mounted in guides 40upon each slider of the cutter carriage and manually operated by meansof a bell crank lever .41 pivoted to the slider and having a handle 4-2.The

latch is adapted to engage in a recess 43 of the plate 44, which issecured in a vertical position to the carriage bed adjacent the end ofthe latch. This plate is provided with a vertical groove 45, and securedto the bed plate by means of screws 46 passing through this recess. Toconveniently adjust the latch plate 44, a vertical screw 47 is mountedto rotate on a lug 48 upon the bed and to engage in a lug 49 upon theplate, lock nuts 50 upon the screw being provided to engage against thesides of the lug upon the plate to lock it in any desired position withrespect to the screw, the lower end of the screw being retained againstlongitudinal movement in the lug upon the bed. By this arrangement thespindles may be locked in a predetermined position vertically by meansof the latch, and the latch plate may be adjusted to change thisposition according to the requirements of the work.

Horizontal movement is given to the carriage by means of a horizontalrack 51 (see Figs. 7 and 8) secured to the lower edge of the upperhorizontal guide of the standard, and a gear 52 rotatably mounted on theinner side of the carriage, upon the inner end of a shaft 53 extendingthrough the bed plate of the carriage. Upon the outer end of the shaft53 is secured a disk 54 by means of the key 55, the washer 56, and bolt57 in the end of the shaft. The disk is provided with an outwardlyextending hub 58 upon which is secured the crank 59 carrying the crankhandle 60, the crank being fastened rigidlyto the disk by means of thescrew 61. The inner face of the disk is provided with an annular groove62, the outer surface 63 of which forms an internal cam over which rollsthe cam follower 64 fixed to the upper end of a vertically movable latch65, which is slidably mounted in a vertical slot of the bed plate andprojects through the bed plate, the inner lower end 66 of the latchprojecting over the upper edge of the lower horizontal guide of thestandard, and being adapted to engage in a recess 67 in this edge. Thecam follower actuating the latch is held downwardly against its cam bymeans of a bolt 68 extending downwardly from the latch through anaperture in the bed plate of the carriage, the upper end of the boltbeing fixed into the latch and the lower end of the bolt being providedwith a head 69 having a spiral spring 70 surrounding the bolt betweenthe head thereof and the upper shoulder of the enlarged portion of therecess in which the lower end of the bolt and spring are contained. Bythis arrangement when the crank is turned to move the carriagehorizontally the latch locking the carriage will be automaticallywithdrawn from engagement with the standard during the first part of theturn of the crank, to permit the carriage to be moved, and during thelast part of the turn of the crank the latch will be permitted to bedrawn by its s ring into engagement against the edge 0 the guide alongwhich it will slide until it drops into a second recess provided to lockthe carriage in its second position.

Toprevent the movement of the carriage until the latch is withdrawn, thegear 52 upon the inner end of the shaft carrying the crank is providedwith a key-way 71 wider than the corresponding key 72, whereby when thecrank is rotated in one direction the shaft is permitted to rotatethrough a limited are before the key 72 acts upon the gear 52 to turn itand to move the carriage. Two recesses 67 are provided for the latch tolock the carriage in two positions, and are spaced apart a distanceequal to the distance between the cutters, and the gear moving thecarriage is so proportioned that one rotation of the gear moves thecarriage adistance equal to the space between the cutters, thus givingthe cam a complete revolution as the carriage moves over that distance,thus permitting the latch to be drawn by its spring automatically intoengagement with each recess consecutively. Thus when the machine is onceadjusted either cutter may I be automatically brought into a fixedposition, with respect to the work, with great exactness.

Power is transmitted to the pulleys connected to the spindles by meansof a vertically jointed shaft 73 housed within the standard of themachine. The upper end of this vertical shaft projects through anaperture 74 in the upper side of the standard and is carried in abearing 75 provided intermediate of its ends with a horizontal flange 76 resting upon the upper side of the standard and being movably securedthereto by means. of the bolts 7 7 passing through slots 78 in theflange, the bearing being yieldingly pressed toward the front of the machine by means of a curved spring 7 9 held against the rear edge of theflange by means of a set screw 80 in an upwardly projecting lug 81 uponthe standard. The upper end of this cylindrical bearing 75 is reduced toform a bearing 82 for a driving pulley 83 concentric with the verticaldrive shaft 7 3 which projects above the upper edge of the pulley, andis rigidly connected thereto by means of a collor 84, the weight of thepulley and of the shaft being supported by the standard. This pulley isso arranged with respect to the pulleys connected to the verticalspindles that as the cutter carriage is moved horizontally it brings thefaces of the pulleys consecutively in contact with the driving pulley,and the yielding bearing of the driving pulley prevents any sudden shockor undue stress being brought to bear upon the cutter spindles.

The lower end of the Vertical drive shaft 78 is supported upon an endthrust roller bearing 85 carried within the frame of the standard, andis provided at its lower end with a bevel gear 86.

The counter-shaft S7 for driving the machine is mounted on one side ofthe standard adjacent the base thereof, the inner end of thecounter-shaft being journaled in the side of the standard and beingprovided within the standard with a bevel gear 88 meshing with the bevelgear upon the vertical drive shaft 73 of the machine. The outer end ofthe counter-shaft is journaled at the upper end of a bracket 89, thelower end of which is fastened to the outer edge of the base of themachine. The countershaft carries the usual cone pulley 90, to beconnected to a main driving shaft, and also a pulley 91 to drive theoiling pump.

Means for keeping the cutters constantly lubricated is provided withinthe standard and comprises an oil tank 92, a rotary pump 93, a pipe 941between the tank and the pump and a pipe 95 leading from the pump to thefront side of the standard and having a jointed end 96 to direct theflow of oil against the cutter. The oil tank is located in the frontlower side of the standard just beneath the shoulder below the table.the upper surface of the shoulder being dished and provided with anaperture 97 leading from the bottom of the depressed portion of thesurface into the top of the oil tank. The table also is provided with agroove 98 extending around the upper surface thereof to catch the oil asit flows from the cutter and to return the same through the groove andover the in clined surface 99 of the bed of the table into the basin andthrough the aperture 97 of the standard and into the oil tank 92. Thus asteady circulation of the oil is maintained from the tank to the cutterand back again to the tank. The oil pump has its spindle 100, projectingthrough the side of the standard and carries apulley 101 vertically inalinement with the pulley 91 upon the counter-shaft by which it isdriven.

In Figs. 11 and 12 are shown two positions of a modified form ofmechanism for driving this machine. This construction comprises pulleys,102, as already described, connected to the upper ends of the verticalcutter spindles, and also a driving pulley 103 as already describedconnected to the upper end of a vertical drive shaft carried by thestandard, but the pulley 103 is spaced from the pulleys 102 so as not tobe broughtinto contact with the rims of either of these pulleys throughthe motion of the carriage, and a belt 10 1 passing around pulley 108and between pulleys 102 and over an idler 104 supported upon arms 105rigid with the standard is used to drive the pulleys 102. By acomparative inspection of Figs. 11 and 12 it will be seen that as thecarriage is moved from right to left the pulleys 102 driving the cutterspindles are successively engaged and driven by opposite portions of thebelt 10* In the modified driving mechanism shown in Figs. 13, 14. and15, an idler, 106, is mounted upon a sliding bearing 107 between themain driving pulley 108 and the pulleys 109 connected to the spindles,and the belt 110 in this case passing over the main driving pulley 108and around the outer sides of the pulleys driving the spindles beingbrought inwardly between these latter pulleys and carried around theidler. The idler is drawn rearwardly to maintain the belt always intight condition by means of a rope 111 connected to the sliding bearingof the pulley and extending rearwardly over a pulley 112 and thendownwardly and having a weight 113 connected to its lower end.

In the operation of this profiler, the work is clan'iped to the table ofthe machine to which is also attached the pattern or model to beduplicated and the cutters are adjusted and the carriage is moved tobring the roughing cutter and the finishing cutter consecutively intolocked operative position with respect to the table. The slidersearrying the cutters are each provided with pins, 114, arranged uponopposite sides of the cutter and adapted to serve as guides formanipulating the table to bring the various portions of the patternbeneath the point of one of the pins, thereby moving the workcorrespondingly beneath the cutter to reproduce the contour of thepattern.
